Precision Microdrives Motor mechanisms

Custom motor assemblies designed and manufactured in house

Expedite your motor and mechanism development

Trust Precision Microdrives to manage your development and manufacturing risks

Precision Microdrives offers a full turnkey service, to prepare design inputs, develop a manufacturable solution and mass produce

Motor mechanisms are easy enough to prototype. But with many moving parts, they soon become a real challenge to mass-produce both cost-effectively and to a consistently high-quality standard. Precision Microdrives is a domain expert in this niche discipline.

Speak to an engineer

We offer a full turnkey ODM service 

Preparing design inputs, developing a manufacturable solution, and on-ramping into mass production. Our business is optimised for this very process.


Design for your application

Our design engineers in Europe are in the right place, timezone, and have the right language skills to work very closely with your engineering team. Together we’ll develop accurate specifications and design inputs.


Develop and test

Our product engineering team in Hong Kong have the language skills, supplier relationships and necessary design-for-manufacture experience to develop complex assemblies. They are experts at sourcing individual sub-components from a lower cost Asian supplier ecosystem. They’ll work with our design engineers to implement a solution that we’re all proud of.


Produce and manufacture

Our in-house manufacturing lines are co-located with our Hong Kong engineering team. This is very unusual for Asia, but it makes manufacturing optimisations, process, quality controls, and ongoing production management significantly easier. This is where your mechanism will be built, tested and shipped from.


Medical diagnostics instrument

A robust and low-voltage healthcare mechanism manufactured in-house

  • Hospital lift application, manufactured in the USA.
  • The patient lift was required to lift 350 kgs from an overhead gantry. 
  • Mod 1 gear train, coupling 52mm high torque coreless motor to the lifting drum.
  • Fitted with an encoder for motion control, and a fail-safe electro-magnetic brake.
  • Introduced as part of a product lifecycle update, which lead to increased sales by 36%.
  • Our customer’s engineering resources were freed up to work on new and more valuable future developments.


Heavy duty mechanism for hospital patient lift

A robust and low-voltage healthcare mechanism manufactured in-house

  • Update of a bench-top medical diagnostics instrument, manufactured in Germany.
  • The mechanism cost had to halve, whilst maintaining the same accuracy.
  • X axis positional accuracy to 25 μm (½ of a human hair), and Z axis to 12.5μm (¼ of a human hair).
  • We designed from our library of components, including integrated encoders, home sensors, and custom motion controllers.
  • Our assembly interfaced mechanically directly into the customer’s instrument chassis.
  • Our motion controllers interfaced directly to the instrument’s host processor, over SPI.

Why Precision Microdrives?

Trusted motors and mechanisms

Getting the core of your application correct, first time

Motors and mechanisms are likely one of the most expensive lines on your BOM and also the least likely to be noticed by your customers. Until they fail… 

So, choose an engineering partner that has extensive domain expertise in mitigating the technical risks of these complex products.

Rely on a manufacturing partner with a presence on the ground, robust quality control processes, and a familiar approach to maximising your value-add.

Priced to deliver the best value

We engineer our products to be optimised for your application and delivered at a best value cost.

We don’t engineer our solutions to the highest possible standards, or the lowest possible costs.

That’s not the only way we help your profitability either.

Add a very technically experienced, cost effective addition to your development team. We will free up your internal resource to focus on more valuable R&D work, which will expedite your development cycles.
